I would say spend the majority of your time with your girlfriend because she is your mate but always make time for your friends. You don't want to totally cut your friends off because if the relationship doesn't work out with your girlfriend you may not have friends to go back to. On the other hand you definitely don't want to spend more time with your friends than your girlfriend because she'll feel neglected.

Yeah, actually in the girlfriend..:)
its just that i want him to experience everything he could have experienced when we aren't together, you know, guy stuffs.
also, its like my whole life solely revolves around him.
i think i have a problem. hehe

I would like spending more time with my boyfriend. My boyfriend and my friends get along well enough that we can spend time with them, such as this weekend my boyfriend and I are having dinner with my best friend and her husband.
